+-- To use this module add:

+--     teardrop.toggle(prog, edge, height, screen)
+-- from a keybinding. 
+-- 
+-- Parameters: 
+--   prog     - Program to run, for example: "urxvt" or "gmrun"
+--   edge     - Screen edge (optional), 1 to drop down from the top of the
+--              screen, by default it slides in from the bottom
+--   height   - Height (optional), in absolute pixels when > 1 or a height
+--              percentage when < 1, 0.25 (25% of the screen) by default
